Yes, and lots of sane people don't get married. The existence of the concept of marriage or the fact that it has been a popular tradition in our culture doesn't make it a good choice ipso facto.
Unrelated to that, I came up with a good summary of my marriage philosophy with one of my close (female) friends many years ago. A woman that is good enough for me to marry is a woman that I won't need to marry.
This doesn't mean that I'm opposed to marriage. What it means is that I eye with suspicion any woman who considers marriage as the goal of a relationship, as that strongly suggests fundamentally broken priorities on its face. A lot of guys have not thought about it this way, but they should. Marriage should be a quaint and pointless ritual that you engage in for the heck of it when you have a great relationship, it shouldn't be something that you actively are striving for. Marriage has no intrinsic value, and absent a good relationship, becomes a liability. Too many people get married to "prove" how good their relationship is, when a good relationship should be self-evident with or without marriage.
I am so sorry that you see things this way.
The institution of marriage is getting a bad rap by people who want to change the fundamental underpinnings of our society. They are succeeding in so many ways: abortion, gun grabbing, forbidding prayer, flying planes into buildings, etc.
It is so sad to see this happening.
